http://www.osnews.com/thread?426148I don't know anything about this "Squeeze" encoder, but I'm guessing it's not really as good as x264.

There is really no point in comparing anything to H.264 if you're not using x264 (in the same way that if you are comparing something to Theora, you really should use Ptalarbvorm, or at least Thusnelda).

My guess is that x264 will beat VP8, but the difference will be small, and VP8 will be perfectly suitable for web video.Edited 2010-05-23 11:10 UTCSun, 23 May 2010 11:10:00 GMTdonotreply@osnews.com (Zifre)CommentsRE: Comment by hornetthttp://www.osnews.com/thread?426149
http://www.osnews.com/thread?426149I agree. This test should have been against a well-optimized x264 command line, not a random GUI encoder that has pre-baked options. The reason for this is two fold:

1. The kind of videos people look at mostly, at Youtube & Vimeo, are using these well-optimized command lines to encode (youtube is using a modified x264 version, and Vimeo is using x264 via mencoder AFAIK). Therefore, it's these kinds of videos that will essentially matter on web video. What you and me are encoding at home will always be good enough with either encoder (really, do we need better quality recording our cats sleeping on a couch?), but web broadcasting is where the difference is made. And since these web broadcasting services are always well-optimized, I expect any benchmarking test to try to be as close as possible to the level of these web services.

2. The guy possibly did use the command line to encode to WebM, so why not for h.264 too?

I know that the x264 developer was called biased for his recent blog article that was linked from many places, however, I don't think he was lying. When he said that VP8 is possibly as good only as h.264 Baseline, I think he was truthful in that.

Still, I rather have VP8 (even on my camera, shooting directly to VP8) than have the patent nightmare and ESPECIALLY the crazy licenses for cameras/video-editors surrounding h.264.Sun, 23 May 2010 11:11:00 GMTdonotreply@osnews.com (Eugenia)CommentsMainconcepthttp://www.osnews.com/thread?426150

http://www.osnews.com/thread?426152I all, here you can find a comparison between H.264 (x264 encoder) and VP8 encoded videos. We used the latest VP8 library version from webm project:

Therefore the h264 version is the one most likely to have been optimized "by hand", but I don't think it is. It is also unlikely that Squeeze uses x264 because the former is licensed while the second is open-source*.

http://www.osnews.com/thread?426172It's hard to compare h264 to vp8... because it's like comparing trees to rocks... Each technology has it's strengths, but in the end, they're both depended of encoders and decoders, the first ones are pretty strait forward to compare, but h264 has mature encoders and vp8 doesn't have many yet (but will, due the interest to WebM/OpenSource)... also, h264 is a pretty big standard, it has profiles to mobile devices, to pcs, to media boxes and bluray players, but also for authoring, also pretty much decoded equality, but requiring more processing. VP8 is more of a deliver to costumer codec, it doesn't have as many options, and also, much of the work done by profile levels in h264 is done in VP8 by the decoder, in post-processing (so, mobile clients may use less intensive post-processing when more powerful clients can use more intensive post-processing.), actually, it's heavy dependent on this post-processing process.

...in the end, one should read this articles as a preliminary view of codecs differences, and one should probably prefer articles offering more information about the tests, the encoder as the renderer than simple screenshots at this time.

I'm convinced YouTube will switch to the new codec exclusively as soon as WebM support is added to Android (Gingerbread, Q4 2010) - if only to spite Apple

So Google, while having a member on the Apple board, get the YouTube app included on the iPhone using h.264 and now that they have released their own smartphone platform in competition they buy and release a codec that, if the above prediction is true, would effectively render a built-in iPhone app inoperable and significantly benefit Google's own platform in the process, yet nobody seems to think there is anything anti-competitive let alone unethical about this?

As much as I'd enjoy (and already enjoy) the vision of Apple finally getting slapped in the face for all of their horrible business practices, and the MPEG-LA's patent trolling and FUD put to an end, what you say here makes a lot of sense. You can't ask me to defend the GIF of video formats, but it's more than fair to declare that Google will use this to increase its monopolistic power.

And then I wonder (and it's a real question, not some trolling) : what can we do against Google, when they're always the most reasonable choice ?

Being a bit worried about them one day, after enumerating all the Google-owned services which I were using, I reduced my Google consumption, going as far as trying other search providers like Yahoo and Exalead (still using YouTube and GMail, though). But then, every time I use Yahoo, I see horrible interface design along with poor search results, and I think "those guys don't even understand what an user asks from a search engine".

I, as a geek, will then choose to use the clunky service. But I can't honestly recommend them to anyone else. If someone asks me "What are the benefits", I'll say "Google does not own you", and if someone asks me "...and ?", I'll say "Nothing else, in fact you'll rather lose a lot".

And indeed, saying "no" to Google means losing a lot for just about everyone. It means losing the best search provider in the world, the most complete video sharing service in the world, the guys who helped open-source going twice as fast lately through the GSoC system, an easy-to-use free and ad-free blogging service, the sole flash-free map service which I know of, the sole H.264 alternative that's able to stand against the MPEG-LA's patents, and so on... Sometimes I lose faith and think that saying no to Google is related to masochism.

What benefit, other than experiencing that we've still got some freedom, does one get from that ?Edited 2010-05-23 15:09 UTCSun, 23 May 2010 15:05:00 GMTdonotreply@osnews.com (Neolander)CommentsRE[3]: More legal challenges ahead...http://www.osnews.com/thread?426180

there is a difference btw a codec spec and codec encoder. A bad spec will do badly independently of the encoder used and a bad encoder can produce a terrible video no matter how good the spec is.

Blogs like osnews should try to show a distinction btw a spec and an encoder.

Looking at the "park joy" example provided by the second comparison the x264 encoded image is visibly sharper than its VP8 counterpart, especially in parts with lots of foliage and grass (i.e. small details). I'm not familiar with the encoder settings so I would like to know if the settings used for x264 produce encodings compatible to the baseline profile.

That's to be expected. A similar (or same?) scene was used to show the improvements in Theora - this was also less blurry after the codec was improved.

VPx codecs generally tend to blur the image to save bit. I guess VP8 can fix that just like Theora (being based on VP3) didEdited 2010-05-23 19:36 UTCSun, 23 May 2010 19:35:00 GMTdonotreply@osnews.com (pgeorgi)CommentsComment by Radiohttp://www.osnews.com/thread?426211
http://www.osnews.com/thread?426211The http://www.quavlive.com/video_codec_comparison has been updated, and VP8 is as good (or, maybe, as bad) as h264 encoded with the libx264 (is it x264?) on a visually complex video. The bitrate of the output is different from the one entered in command line (rounding?), and is always lower with VP8. Also, the size of the video file is always smaller with VP8. Both are beneficial for streaming.

Notice that the x264 video done by quAVlive, on the same video "park joy", is noticeably worse than the ones done by the x264 dev Dark Shiraki:

http://www.osnews.com/thread?426230The Park Joy video is an extremely difficult one to encode, which is why it's often used in the these encoder tests. Note that in addition to the high level of motion and detail present, it's running at 50 fps. So for a standard video, you would cut the bitrate in half and have identical levels of quality.

VP8 clearly looks blurry in that video when you take a screenshot and compare them side by side. When you view the video in motion, though, it's tough to spot any difference unless you are really trying to spot it. And the other video with the bee shows that there's really no difference in the result for some easier videos.

Irrespective of the openness of VP8 this is categorically a case of someone abusing their market position to force a market's direction.

I realize you have issues comprehending anything business, so let me clarify for you. IMPLEMENTING an open and royalty free codec is fine. Great in fact. SWITCHING on the other hand is a problem if it damages your competition in another market. It would be like Microsoft going into the hard drive business and restricting Windows to only support hard drives from the company they set up. Worse in fact, because at least the existing Windows users could keep using what they had, unlike the existing iPhone users who's app will be broken.

http://www.osnews.com/thread?426260I understand what you're trying to say here and you have a couple of good points, but you're missing some important stuff as well.

Google is already restricting Youtube to a single format, so switching doesn't restrict anything further. In fact, I'd guess they'll probably keep a 360p copy around in h264 just for compatibility, at least for a while. They can get away with saying you'll need VP8 support if you want the higher resolutions.

Also, I can guarantee you that Google themselves would write the VP8 acceleration code if Apple allowed them. Heck, Apple could just allow Flash to run on their phones, and that would be taken care of for them by Adobe. Also, isn't that kind of the point of writing a mobile phone OS? What are we paying Apple to do, if it isn't to enable content support in their OS? No one is stopping them from implementing the support, just like we expect them to ship the phone with a browser that can view most websites on the internet without problem. So I think that argument is fairly weak.

Where I think you do have an argument is that Google has the power to change things maliciously, and that would indeed be bad. I just don't think they are here.Mon, 24 May 2010 08:26:00 GMTdonotreply@osnews.com (smitty)CommentsThom *might* be blindhttp://www.osnews.com/thread?426261

Apple as a company has managed to segment out a group of customers that are both wealthy and stupid at the same time.

Apple's fault.

Apple knows perfectly well that the policy for web standards, and hence HTML5, is "ROYALTY-FREE", yet Apple still shipped millions of i-devices with no support for open codecs, but instead supported only a patent-encumbered codec.

The W3C Patent Policy governs the handling of patents in the process of producing Web standards. The goal of this policy is to assure that Recommendations produced under this policy can be implemented on a Royalty-Free (RF) basis.

Apple's fault. Apple should pay the cost.

Perhaps Apple can ask Google to code a VP8 accelerator for the iPhone/iPad/iPod, and Apple can then upgrade everybody's i-device for free.

Patents and pricing aside of course, I am just discussing the technology here, since that is what the story is about.

You prefer artefacts that aren't there? When things are moving, people see blur. Even cameras see blur.

Your examples are very high resolution. People don't have that much bandwidth on the net, they would be watching that video at one frame every ten seconds. (We are talking here about a codec for the web, not for a blueray player).

To give a little more bandwidth to high-motion areas and de-blur (without introducing invented artefacts) is a matter of tuning (of the encoder only). Activity masking and Altered Skip weighting are techniques that have helped Theora improve recently, and at first blush these look as if a bit of tuning might also help VP8.

The basic, unpolished VP8 encoder performance is almost indistinguishable from H.264. A bit of fine tuning of the encoder here and there to polish out effects like these, and it will be sweet. Just discussing the technology here, there is absolutely no reason why we should invoke costs for 99.9999% of the people on the planet, and direct money to 0.0001% of the people, just for the sake of a bit of fine tuning of the VP8 encoder.

Oh, and because the fine-tuning needs to be done only to the encoder, people can go ahead with the decoder (player) software embedded in browsers right away.Edited 2010-05-24 10:53 UTCMon, 24 May 2010 10:52:00 GMTdonotreply@osnews.com (lemur2)CommentsRE[4]: H.264 vs VP8 comparisonhttp://www.osnews.com/thread?426276

In 1 and 4, H.264 was obviously superior. 2, 3, and 5 I couldn't tell a difference in quality (H.264 is a bit blocky in its shadows, but VP8 smoothed those over a bit too much, or made it splotchy--very much a draw), and 6 looked better with VP8. In #1, look how much clearer the man's wrinkles and dimples are in H.264.

So, for web streaming: it's ready right now.

2nd comparison:
Even my Superbit DVDs aren't all up to 7.5Mbps. I'm not terribly enamored with HD, I guess. It would also have been nice to just see the saved 480 frames at 100%, too, rather than scaled up. Some of the live frames are fuzzy, but not too bad. I'll stay optimistic about the encoder. The live video as a whole looks quite good, IMO.

For high quality video: the encoder needs some work, but it's not bad.

Most of the, "indistinguishable," Theora videos looked like Hell with any real motion. VP8 seems to be up to the task of competing with H.264, and is free, to boot. Let's give it a year to spread around, get a more mature encoder, and so on, then ditch H.264, and rejoice.Edited 2010-05-24 11:34 UTCMon, 24 May 2010 11:18:00 GMTdonotreply@osnews.com (cerbie)CommentsRE[5]: H.264 vs VP8 comparisonhttp://www.osnews.com/thread?426283

The original claim was...
"Today GIF is used almost exclusively for its animations, since no other means of animation is natively supported by all browsers.

It does not claim that PNG does not animate. Just that not all (common) browsers support it, unlike GIF... "

The quote that you give says that apart from GIF, no other means of animation is natively supported by all browsers. That is not a statement that PNG does animate.

The other statement made was actually about PNG. I quote: "PNG is superior to GIF in almost every way. It does not animate and under certain very specific scenarios has inferior compression. Other than those it is superior."

My bold.

We have one statement that PNG does not animate, and another statement that only GIF animation is supported by all browsers. Neither says that PNG can animate, when actually, it can.

Although the second statement is true, that does not mean that the first statement was right.Edited 2010-05-24 12:47 UTCMon, 24 May 2010 12:42:00 GMTdonotreply@osnews.com (lemur2)CommentsRE[3]: H.264 vs VP8 comparisonhttp://www.osnews.com/thread?426313

I can't tell what's actually a true detail and what's just an artifact on the H.264 one. The grass and trees look more "detailed" but on the human figures they just look a different kind of odd.

Is the extra detail on the trees just an illusion? It looks like someones run a sharpen filter over everything.

http://www.osnews.com/thread?426314I wonder if this is really true. I have yet to find a single decoder that works this way. Do you know of any chip that works in this way? in that case i would be glad if you could name it so i can look it up i try to follow news letter from ic makers.

I think the big reason for this are first it complex to make a chip that implements the whole h264 in hardware ex that you just can stream h264 to the chip and get decoded frames in return. second if it implements h264 in firmware then the chip makers would have to pay mpgla.

however if you just make a chip that can handle the math behind h264. you can leave constructing a h264 library to the manufactures and you should be clear from infringing patents.

http://www.osnews.com/thread?426319When I was looking at the linked page, it already contained comparisson to x264, and the images could be clicked to open the full resolution version. My monitor happens to be 1920x1200 and with my browser fullscreen, I can look at them unscaled. Loading them in two separate tabs, I can flip forth and back.

With the bee, I agree the difference is almost not noticable, I think x264 has less block artifacts, the gradients are somewhat smoother.

However with park scene, I have to say the difference is staggering. x264 is playing in a whole different league. There is soo much more detail in all the plants and suroundings.

They can support the codec without hardware acceleration and the iPhone gets horrid battery life playing YouTube stuff, or they reprogram the DAC to give VP8 hardware acceleration and the iPhone's battery goes into meltdown playing content from the iTunes store.

Wow, Apple uses DSPs that are only capable of supporting a single codec? Let me guess - they had the opportunity to get more flexible DSP chips, but Steve didn't like the color they came in (it clashed with the logic board, so tacky!).

Irrespective of the openness of VP8 this is categorically a case of someone abusing their market position to force a market's direction.

No one else is getting all whiny and defensive over WebM, I don't see Palm, Microsoft, Nokia, Adobe, nVidia, ARM, etc (or their advocates) crying about it. Should Apple get special treatment because their h.264 lock-in agenda has been undermined?

Only a few weeks ago you were wanting Theora to be the standard, now VP8

Uh, it's called being sensible. Let me spell it out for you: WebM has the exact same virtues as Theora, and an infinitely better chance of succeeding. So you're criticizing Thom for supporting a codec based on merit, rather than being a blind Theora fanboy.

so I ask you this, how much chance does a codec like Theora have with Google doing this?

Buwahahahahahaha! What chance did it have before? Oh, and who can we thank for that?

It's amazing that you accuse Google of anti-competitive behavior and then mention Theora, which Apple has done more to hinder than anyone else (by refusing to even allow 3rd parties to support it on the iDevices).

Tell me, what sounds more like anti-competitive behavior:

Google releasing a royalty-free codec, that Apple or anyone else can implement so long as they don't try to pull an SCO.

- or -

Apple holding back the adoption of a royalty-free codec (Theora) by refusing to support it & lobbying against its standardization by the W3C, in favor of a codec that Apple just happens to have a financial interest in via their membership in the MPEG-LA.Mon, 24 May 2010 17:54:00 GMTdonotreply@osnews.com (BallmerKnowsBest)CommentsRE[4]: H.264 vs VP8 comparisonhttp://www.osnews.com/thread?426332

Gif is a lossless 8-bit (usually) color indexed format that is great for simple computer graphics and illustrations. JPEG is a lossly (with exceptions) 24-bit format that is great for photographs but terrible for illustrations.

I know what GIF is. However, let's go back to those times. When you were making an average personal website (that looked horrible), if you wanted to put a little graphic as a button, you had two choices :
-> Gif (smaller file size in most cases, pretty close to the original file, supports animation)
-> JPEG (big or ugly, no animation)

So GIF was the superior format for most little images on the web. JPEG is good for photographs, but it can also be used for illustrations, even though it does a terrible job.

http://www.osnews.com/thread?426454Since I made the original statements let me clarify: PNG cannot animate. Is that clear enough? APNG can, MNG can, PNG cannot. Sure APNGs can be displayed as PNGs by browsers not supporting APNG, but that doesn't change the fact that PNG doesn't animate. If you have a PNG-supporting browser and load a PNG file in to it you will not get animations. If you have a PNG-supporting browser and load an APNG in to it... you will not get animations. APNG or MNG must be supported to get animations.

GIF, as a format, natively supports animations. PNG does this only through a kind of extension; an extension which is not supported natively by all browsers.

So, I reiterate, PNG is superior to GIF in almost every way. One way in which it is inferior is that it does not animate. Support for animated image formats other than GIF is not universal across common browsers.

http://www.osnews.com/thread?426759I just gave a quick look to the "Park Joy" videos (the videos themselves and not the still images) on the quavlive link. My conclusions:

- h.264 has a lot more artifacts than VP8;
- on still screenshots, h.264 wins in all cases;
- on (almost) all resolutions (in motion), both codecs seemed the same;
- the exception was SD video, which seemed strange in h.264 and more "natural" in VP8.

At least it is my opinion, but who cares? Here is my opinion about the much more interesting topic of the codecs themselves:

- The visual output of each one is incredibly different on low framerates;
- Yet, both are able to reproduce the intended image!
- So, they are not comparable;
- This happens because for us to compare them, we would need an objective way of deciding which are good and bad losses.
- We don't have that.
- So, opinions on how close to reality it gets will vary from person to person.

At least it is my opinion... on something much more interesting than a boring comparison of different moving images.Wed, 26 May 2010 23:39:00 GMTdonotreply@osnews.com (ptmb)CommentsRE[11]: H.264 vs VP8 comparisonhttp://www.osnews.com/thread?426762

Early versions of GIF did not support animation. Just as you need an "extension" to the basic PNG functionality to support APNG, so to did you need an extension to basic GIF in order to support animated GIF.

PNG and APNG are superior to GIF.

One can animate PNG alone (i.e. no browser support required for APNG) by using Javascript.

This requires only a sufficiently capable, fast and correct implementation of Javascript, and PNG, which is supported in all browsers except IE.Wed, 26 May 2010 23:59:00 GMTdonotreply@osnews.com (lemur2)CommentsRE: They are different codecshttp://www.osnews.com/thread?426764

Exactly. People actually see motion as blur. There is no real point in precise sharp definition for parts of the video which are in high motion ... people are going to see it as blur anyway.

These observations also highlight that there are major differences in approach between h.264 and VP8. The codecs use distinctly different methods to achieve the same end (compression of digital video data). Ergo, one would surmise that these codecs do not infringe on one another's patents.Thu, 27 May 2010 00:16:00 GMTdonotreply@osnews.com (lemur2)Comments
